Evidence points to Xie's guilt: Crown

The combination of evidence against Robert Xie inevitably leads to the conclusion that he murdered five family members, a jury has been told.

"This is why we say to you, your verdicts, there are five, in each instant should be guilty," said prosecutor Tanya Smith.

She was concluding the Crown's final address at the NSW Supreme Court trial which began on June 29.

Xie, 52, has pleaded not guilty to murdering five relatives of his wife in their bedrooms at their Sydney home in the early hours of July 18, 2009.

He is accused of using a hammer-like object to inflict horrific head injuries on his newsagent brother-in-law Min Lin, 45, his wife Lily Lin, 43, her sister Irene, 39, and the Lins' two sons, Henry, 12, and Terry, 9.

The Crown says Xie was motived to kill them out of jealousy, being infuriated with his perceived "subordinate status" within the extended family.

On Wednesday, Ms Smith listed the main pieces of evidence the Crown relied on to establish that "the single assailant who killed the five members of the Lin family was the accused".
